We’re kicking off an animated series that takes a quirky look at the fundamentals of molding. The first short video is on draft, one of the most important consideration during injection molding part design.

Look for lots of high-tech touches at this Sunday’s Super Bowl, organizers have promised. More than 72,000 fans are expected to attend the game at Levi’s Stadium in Santa Clara, California near San Francisco, which is home to the NFL’s 49ers.
At the Game
As CNET reports, most of those in attendance will likely be using some sort of mobile device as they look at game statistics and share photos and other content on social media. To handle all of that data, the stadium, which opened in 2014, has 400 miles of fiber and copper cable and 1,200 Wi-Fi access points. The venue has 10 times more bandwidth than the NFL mandates at other stadiums.

On the app side, those at the game can also use NFL Fan Mobile Pass and the Road to 50 apps to help them get around outside and inside the stadium.
Video is also central to the stadium’s technology infrastructure, says the San Francisco Chronicle. A video master control room runs everything that fans see on two giant scoreboards, a video ribbon board along the second deck and 2,400 TV monitors throughout the stadium. The room is filled with about $6 million worth of video equipment, including 4K-resolution ultra-HD cameras, instant replay machines and digital video monitors. Continue reading
Many factors come into play when comparing the material properties of thermoplastics found in injection molding versus “thermoplastic-like” materials used in a 3D printing technology like stereolithlography (SL). At Proto Labs, a thorough selection of thermoplastic-like materials are offered through SL, but what may surprise you is the versatility and range of potential applications for SL parts.
This month’s tip discusses:
- heat deflection, tensile strength and other important properties of thermoplastic-like materials
- how SL materials compare to similar injection-molded thermoplastics
- the benefits and range of suitable applications for each SL material
- the impact of light and moisture exposure on 3D-printed parts

Auto fact #1: About 50 percent of a modern car’s volume is plastic yet it only accounts for 10 percent of its weight
Auto fact #2: 43-year-old men purchase more cars than anyone else.
Stats like this bring to life the changes taking place in the evolution of the automotive industry, as research and development move at a pace faster than ever.
Two major factors are driving these changes: regulations and market demands. We are all familiar with automobile safety regulations, but may be less familiar with CAFE (corporate average fuel economy) standards. These standards set mileage requirements for an automaker’s fleet. The 2025 target is 54.5 miles per gallon.
Now think of the 40-something guy that represents the largest demographic who are purchasing cars. Is this individual willing to give up performance, e.g., acceleration or leather seats or integrated entertainment systems, so that his new ride meets mileage and safety requirements. Probably not. Innovation is often times driven by necessity and the automotive industry is responding.
BMW started using magnesium for its N52 six-cylinder crankcases and cylinder head covers in 2005.
In recent years, there has been a major push around lightweighting to help address mileage requirements. Weight reduction is one proven method to improve fuel economy and minimize the impact on performance. This can achieved through the use of engineering-grade resins that possess physical properties well beyond what the average consumer thinks is possible.
The commercial-grade Indago Quadcopter unmanned aerial vehicle (UAV) or drone, from Bethesda, Maryland-based Lockheed Martin, is soaring in popularity with law enforcement agencies, defense customers, firefighters, real estate firms, farmers and construction companies.
The high demand stems mostly from the drone’s versatility, range and small, 5-pound, fold-up size, says Miguel Perez, an engineer for Lockheed’s Procerus subsidiary, which developed the drone with prototyping and low-volume production help from Proto Labs.
Lockheed Martin’s Indago drone is a small, 5-pound, fold-up quadcopter capable of work at various ranges — up to 1.5 miles (2.5 kilometers) using integrated antenna solutions — from its ground controller.
